Conversely, TRQ (4 ml/kg, 6 ml/kg and 8 ml/kg) administration inhibited LPS-induced M1 marker gene expression (TNF-α, IL-6, IL-1β, iNOS and MCP-1) and enhanced M2 marker gene expression (Arg-1) in the lungs of ALI mice (Figures 9H, I). The gene discussed is ARG1; the disease is acute respiratory distress syndrome.
